It's pretty elaborate, showing the inside of the spaceship made famous by the TV series. The crew is approaching planet Notax, which the characters, including Mr. Spock, say has many problems including "alien identity theft."

But since CBS revealed that video and another parodying Gilligan's Island cost tax payers $60,000, the agency has said its making was a mistake.

CBS reported:

"IRS Acting Commissioner Steven Miller said in a statement that one of the two videos was played in 400 locations and saved taxpayers $1.5 million over what it would have cost to train employees in person.

"Nonetheless, the IRS issued a statement that reads: 'The space parody video from 2010 is not reflective of overall IRS video efforts, which provide critical information to taxpayers and cost-effective employee training critical to running the nation's tax system. In addition, the IRS has instituted tough new standards for videos to prevent situations similar to the 2010 video.'

"In response to the release of the Gilligan's Island parody, the IRS said in a statement, 'This approach reflects a newer IRS model of using video to dramatically save on training and travel costs. Using video provides a more cost-efficient way of doing business than face-to-face meetings.'"
